How to Prevent a Dove Bird From Nesting on a Windowsill
- 1). Use a caulking gun to apply lines of bird repellent gel to the windowsill. Scrape off the old gel and spread new gel every six months, when the old gel starts to lose its stickiness. The stickiness of the gel will discourage doves from landing and nesting.
- 2). Hang screen, cloth, or plastic netting from the top of the window overhang, so doves cannot land on the windowsill.
- 3). Cover the windowsill with wire spikes made to stop birds from landing.
- 4). Make the windowsill an impossible place to nest by placing a board on the sill that makes its surface sharply angled rather than flat.
- 5). Frighten away the birds. Hang clear plastic strips from the window overhang; they will flutter in the wind, scaring the birds. Play recordings of frightened birds and of predator birds.
